Since some times I’ve more and more problems when duplicating a block! in fact I receive this message: ![Capture d’écran 2026-04-07 à 19.14.21](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/6/0/6009daa4dba68e28acf896dbdcc1e3ea272b6e5e.png) I don’t understand why! I’m just duplicating a normal block! The problem is that if I ignore the above message then the app don’t function anymore the way it should. Hence, what should I do? Try to modify my code in the actual App or start from scratch a new App which is quite ennuying… Someone could help ? ---
